ERCOLINA’S TM76 mandrel bender is
suitable for prototype or daily production
purposes. CML USA, Inc, North
American supplier of Ercolina tube, pipe
and profile bending and metalworking
machinery, has introduced the TM76
with a bending capacity to 3" round tube
and capable of bends to CLR as small
as 1.5D.
This model offers unlimited storage
of bend programs, material library and
job information with USB. Controls are
designed for easy access to manual
and auto operating modes, system
Fontijne Grotnes builds specialised
production equipment that can be used
in complex manufacturing processes
and has been active in the metalforming
industry for more than 100 years.
Its sizing technologies, consisting of
expanding, shrinking and rollforming
processes, are a valuable contribution
to diverse production processes, to
calibrate and form different parts such as
rings, cylinders and cones, which require
tight tolerances. These processes often
eliminate machining and fabricating
steps, save time and material and
thereby improve operational efficiency
and profitability.
Fontijne Grotnes expanders and
rollformers are widely used to form
finely detailed profiles in cylindrical or
conical shaped blanks from tubing, pipe
or coiled and welded sheet metal.
To form a profile the blank is
positioned around the collapsed dies of
the expander, which have the desired
profile. Cone and drawbar are in the
extended position. As the drawbar pulls
the cone down the inclined surfaces
of the cone force the jaws and dies
outward. Outward expansion stretches
the part past its yield point to the
TM76 mandrel bender
diagnostics and multiple languages.
The interactive touch screen displays
absolute (ABS) or incremental (INC)
positioning with inch or metric readout.
Model TM76 incorporates programmable
mandrel positioning with anticipated
mandrel retraction, clamping, pressure
die and boost die movements. Tailstock
Y and B position display resets to zero
after each bend for easy setup while
maintaining absolute position.
Patented by Ercolina, finger style
clamping system minimises distance
between bends. A heavy, one-piece
steel structure improves rigidity and
minimises vibration.
Ercolina’s tubing benders and
fabricating machinery are designed
to reliably and accurately produce
applications, improving product quality
and finish.
